Role of pre-incubation in non-selective medium in recovery of Staphylococcus aureus from swimming pools and beaches.
Staphylococcus aureus was isolated from eleven open swimming pools and eleven swimming beaches in certain areas of Saudi Arabia. Pre-incubation of the water samples in a non-selective medium prior to their growth in the selective medium increased the rate of recovery over that of direct plating on the selective medium. The average increase was from 20.68% to 46.1% for pools and from 32.7% to 37.3% for beaches. Pre-incubation, therefore, is very important for the pool water which appears to contain more stressed bacteria.
